Admission control plays an important role in providing Quality of Service (QoS) guarantees for wireless mesh networks (WMNs). Multipath routing can improve network performance in reliability and load balancing. However, when the multipath routing are adopted in 802.11-based WMNs, the transmission with bandwidth assurance is facing rigorous challenges. In this paper, a novel joint design of multipath...
We analyze the performance of six export policies for a multi-domain routing protocol in WDM networks. We show that providing many AS-disjoint paths for survivability and load-balancing does not necessarily guarantee the lowest connection blocking.
High rate and high quality of service as well as multi-technology connections are the key words for the future home networks. For this goal, we introduce a new convergence layer denoted inter-MAC, which provides a common infrastructure to the home network at layer 2. Among the inter-MAC functionalities, we focused our interest on the path selection mechanism. To improve quality of service, we define...
DCUR follows the same procedure as define in Bellman-Ford but uses two vectors, namely least cost and least delay vector. The main drawback of DCUR is its assumption of link costs. It means that the minimum cost path is more often chosen and therefore the load distribution is not fair for the minimum cost paths. In this paper we propose a way to modify the cost and delay metrics dynamically in the...
It is very necessary for mobile ad hoc networks to have an efficient routing and quality of service mechanism to support diverse applications. The routing algorithm in the MANETs should also try to balance the network load. Research in this paper combines the multi-constraint QoS mechanism with the load balancing scheme to search the satisfying path between the source node and destination node. The...
Mobile ad hoc networks (MANET) are comprised of mobile nodes that are communicating via either directed wireless links or multi-hop wireless links through a sequence of intermediate nodes. The multipath routing in mobile ad hoc networks is difficult because the network topology may change constantly, and the available alternative path is inherently unreliable. So far, much of the effort of multipath...
A novel autonomic area reconfiguration mechanism is proposed that complements hierarchical QoSR protocols in wireless access networks. The proposed mechanism revises the border between adjacent areas based on handover rates and on resource consumption in terms of bandwidth and user population. Its objectives are concentrated on reducing the overhead related with frequent inter-area handovers as well...
